4.Chemical Bonding and Molecular Structure
normal
Thermal decomposition of $AgNO _3$ produces two paramagnetic gases. The total number of electrons present in the antibonding molecular orbitals of the gas that has the higher number of unpaired electrons is. . . . .
A
$2$
B
$3$
C
$4$
D
$6$
(IIT-2022)
Solution
$AgNO _3 \rightarrow 2 Ag +2 NO _2+1 / 2 O _2$
– Both $NO _2$ & $O _2$ are paramagnetic
$- NO _2$ is odd electron molecule with one unpaired electron
$- O _2$ has two unpaired electrons
Total number of antibonding electrons $=6$
